MEASUREMENT PRINCIPLE
The TZA200 amplifier employs precision
single ended transimpedance input stages
to provide for low offset and high linearity
throughout the full dynamic range. The
single ended input stage is required for
applications where the current source is
inherently grounded externally.
FIELDS OF APPLICATION
TZA200englRevC1.doc
These transimpedance amplifiers are
particularly useful for the measurement of
current from photodiodes. The output is a
voltage linearly proportional to input
current and thus, to input power in
photodiode monitoring applications. The
fast response time at high signal-noiseratio makes the TZA200 series particularly
useful in systems control feedback loops.

These amplifiers have a particularly high
bandwidth of 10MHz allowing monitoring
of high frequency noise components of
many light sources.
The TZA200 series is insensitive to
electromagnetic interference by design, an
important factor when working in „dirty“
industrial environments. These units are
provided in OEM-style enclosures. The
case wings provide for mounting on
standard 25mm and 1“ optical table tops
and for OEM applications.
